- SYNCHBONIZING PICTURE-EXHIBITINQ AND SOlfND-RECORD MACHINE.

.To all whom it may concern Be it known that I, Isrnoa'KrrsrEn, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented .certain new anduseful Improvements in Synchronizing Picture-Exhibiting and Sound-Record Machines, of which the following is determined number proved acommercial success.

a specification. My invention relates to an improvement in synchronizingmoving. picture machines and machines adapted to produce sounds. It isunnecessary here to enumerate all the attempts made in this direction,but so ,far, none of the'devices placed on the market Insuch s stemswhich were brought before the pub ic, the aim of the designer orinventor was to allow the picture film to run at its required speedandto produce means whereby the speed of the talking machine shouldaccommodate itself to the speed of the picture film.

In contradistinction to so far, I accommodate the speed of the picturefilm,v to the'speed of the sound machine and produce means whereby foreach predetermined length of a sound-record a preof picturesareexhibited and" exhibited simultaneously with the production of the soundthrough that part of the record line. \Vhen, either through .design oraccident, the sound machine either retards or accelerates, theexhibition of the film will also'retard or accelerate in the sameproportion;' and if, by design or accident, the sound machine entirelyceases its movement, then the'picpictures on the picture -ture machinewill cease its movement simultaneously. 5 I

For the purpose of illustrating my inven- --t-ion, I have reference tothe accompanying chine.

In Fig. 1; 1 are the meansto operate the picture machine. here shown asan electric motor, of which 2 and 3 are the wires adapted to beconnected to a current carrying circuit. For the purpose of myinvention, it is immaterial if the speed and force 2. this motor areabove the normal and to actuate this motor, it is only necessary toconnect thesame to one of the well known light cir-' cuits. A motor,which takes one-half an ampere at one hundred and ten volts, suffioesfor all practical purposes. 4 is the shaft revolved by this motor. 5 isa frictional drive device as an entirety. The diiferent parts of saiddevice are illustrated in detail in Fig. 2. The function of thisfrictional device is, to allow the motor to normally rotate at a desiredspeed, even if able devices. 6 is an additional shaft on which arepositioned the sprocket wheels 9, 9, for driving the picture and part ofthe means for retarding the movement of said shaft. As clearlyillustrated, part of the frictional device is mounted on the shaft 4 andart thereof mounted on shaft 6. 7 is the light aperture through whichthe light rays project and across which the picture film 8 passes. Thisbeing common to all of the picture film apparatus. it is not necessaryto o into detail of the operation of same. he portion of theinterrupting means positioned on shaft 6 are designated as an entiretyby the numerallO. These means consist here of the stop wheel 11provided. with the four stops 12, 12", 12 and stop, one picture isbrought to view for the purpose of being exhibited on a suitable screen.13 is the partof the interrupting device placed in juxtaposition and inopried by the shaft 6. This rt 13 comprises here two elect-romagnetsesignat-ed by the numerals 14 and 14, respectively, and provided withthe two cores 15 and 15,'respec "tively. The coils 16 and 16"areconnected together atone terminal and to this termithe mechanism, withthe aid of which the film 1s operated, is kept stationary bysuitmovement from one stop to the'succeeding' erative relation to thecooperating part carcrates the film 1n the same manner as the wellterminal of coil 16 is connectedto wire 18 ture which is positionedbetween the two gage the sto hsup osed that the electromagnet 16 is as:

The "wire 18' ofthe electromagnet-lt 4 shown as brush 38 'and the 14 is.h ere shownas'connected to wire 41 of 'brush 39. For the convenience of the'opera-Itor, 'I'haveprovidedthe sound'record with t the mark and -the operatorpositions t that in 'practice,

It is supposed that the brush 39 touches. before the motor 30starts, one of the conducting segments'of the commutating part 36'.

it is supposed the connection of this part of the circuit, the armatureof the device 13 is thrown to the left and in alinement with the stop12; as clearly illustrated in Fig. Land that a blank space'of the filmis brought to view. As stated above, as long as the motor 30 remainsidle, the icture film will remain inthis position. It

as to be stated, that in the operation of my device, the motor 1 of thepicture machineis connected .to itssource of' current and, therefore,revolves the operation of the sound producing machine and rcvolvescontinuously no matter if'the mechanism moving the picture is lockedagainst. revolving or not; thus forthereason that the speed of-the"motor should alwaysbe normal at the moment when the locking means areremoved, otherwise, it would take v a unit oftime before the motor hasattained full speed. It is now supposed that "the motor 30 is broughtintojservice and is revolved at the required and predetermined speed.

It is also supposed that the unit of timefor each rev lution of themotor and. the commutator is equal to the unit of time during whichpictures .should' be exhiblted.

Through thisalternate energiz'ation. the armature will be drawn back and forth, thatis, to the right and left and the prongs :24 and '25 will alternatelyengage with ,and disengage from one of the stops 1'2, 12'. 12 and 12.During the time that they are engaged with. these moving picturemechanism will be at rest, but during the time of the movement of the,prongs from right to left. or vice versa. the friction of the device 5sufiices to move the shaft (3 through the power of the motor 1. It will.therefore. be seen that the be an interrupted"one. in the same manner asthe movements are today, if controlled through the Geneva device; and itwill also be seen that for each conducting segment of the commutator onemovement will take place in the moving picture device and each of thesemovements will bring to View a new picture.

Through experiments. I have ascertained that if the sound and pictureshould be S1- multaneously and correctly exhibited, it is best toaccompany each picture. during the time of its exhibition. with a soundproduced by one inch of sound record, when, therefore. the sound recordis of greater or lesser diameter. then it is obvious that-the number ofsegments of the commutator should also be increased or decreased to suitconditions.

I have discarded all ratchet mechanism through the control of a spring.for the reason that with such mechanism, the ratchet arm has to make twomovementsforthe engagement of. each of the stops and such isdetrimental, since, first, the spring control may vary and, second, thatone of the time units is lost and for these reasons and othersnotnecessary to enumerate, 1 illustrated.-
